[pct-l] Bag/Quilt Warmth

[David Thibault]

You may find your bag feels colder on a long trip because you lose body mass
- usually any fat your body has stored goes as time goes on.  This means
your body may sleep colder later in a trip than earlier.   I wish I did a
Body Mass Index measurement before and after my last thru hikes just to see
how dramatic the loss of body fat is.

Anyone in relatively good shape ever have this checked before and right
after a thru hike?  I'd be interested to see what kind of change people have
experienced.  All I know is I looked like there was not a drop of fat on my
body when I got off the trail and I craved fats (dairy) at every town stop.

Day-Late (who has since gained back all the body fat - I need another thru
hike!)
